LEO J. WAHL, OF STERLING, ILLINOIS. 'I

CLIPPER.

Application led June 23, 1928. SerialbNo. 647,249.

To all whom it may concern.'

Be it known that I, LEO J. WAHL, a citizen of the United States, nda resident of range the electro-ma Sterling, in the county of Lee and State of Illinois, have invented certain new and use` ful Improvementsv in Clippers, of which the' following is a full, clear, andv exact descrip, tion, reference being had to the accompany,

ing drawing, forming partici? this specifica` tion.

Myinvention relates primarily to clippers such asare used by barbers for cutting hair, thoughA it is capable of advantageoususe for other purposes as will be apparent to those skilled in the art to which it appertains.

One object of my invention is theprovision of a'device to be operated by an alternating'electric current without the use of a circuit breaker or interrupter.

Another objectof my invention is to aretic coils llongitudinally of the handle to the end that they may be made-of suicient capacity to eliminate heating in operation. p

Another object of. myinvention is to ops erate the moveable clipper blade by means of an armature moving toward and from the axes of the electro-magnetic coils.

yOther objects of my invention will appear and be described in the specification. The novelty of my invention will be hereinafter more fully set forth and specifically pointed out inthe claims.

In the accompanying drawing:

Referring to Figs. 1 and 2, the clipper comprises a handle 1, to the widened front end 0i which the stationary clipper blade 2 is attached and upon the upper face of the latter, the moveable clipper blade 3 is mounted,.botli of lthese clipper blades are preferably serrated as shown.v A pair of electrolmagnetic coils 4 are mounted in the handle 1, .with their axes longitudinally ar- 'ranged therein, these coils being mounted upon a laminated or other suitable horseshoeshaped core 5, which is suitably secured to the handle asK-b screws 6 which pass through the corean into a pedestal 7, (Fig. 2). The electrical connectionsI to the coil 4 consist of a pair of wires 8 one 'ofwhich is connected to one coil, and .theother to the other coil, these coils being connected to ether as usual to complete the circuit.

he core 'projectsirom the coils 4 a suiiicient distance to provide a proper magnetic VIield .for the attraction of the arinature 9 which is U shaped and is carried by a bar 10, the latter being provided with a foot 11 which is attached to and movesthe moveable clipper blade 3, the rear end of the bar 10; being bent downwardlyv and carried by y the spring 12 which is attached to the case 1.

Referring now to Figs. 3 and 4, the coils 4 are preferably mounted one above the other and lthe armature 13 is a straight bar .vertically mounted and carried by the member'14 which is similar in its functions and mounted to the member 10 previously described and is provided with a foot 11 for attachment to the moveable blade 3. ,4

Referring to Fig. 5 one'of the coils 4 is mounted on the stationary pole piece 15 and f the moveable pole piece 16 passes through a :sufficiently large opening through the other coil 4 so that this pole piece may have the required amount of travel without striking the coil through which it passes. construction the pole lpiece 16 is pivotally connected as at-17 to the stationary pole piece 15 and/its free end may be normally moved'` away from the free end of the pole piece 15 by a spring 18 which may be adjustable as by an abutment screw 19 which may pass through the clipper handle or be otherwise suitably mounted. The free end of the pole piece 16 carries the foot 11 for attachment to and operation of the moveable blade 3.

Referring now to Figs. 6 and 7 the armature 9 is attached to the moveable clipper blade 3, by means of foot 20 which carries the upstanding lugs 21 with which sprlngs 22 cooperate the latter being adjustable by means of screws23 to regulate the energy required to move the moveable blade. I n this construction the moveable blade 1s guided as by rib 24 in a suitable recess 1n In this the stationary blade B and is held in con` tact therewith by suitable means such as springs 25. lThe moveable blade and its moving mechanism as well as the stationary blade and its carrying members may be pivotally connected to the casing or handle l, the pivotal point being arranged as shown at E26 to the end that the clipper blades may be angularly moveable with relation to the handle to accommodate various conditions oi service, and the'meeting portions or" the handle and blade carrying members may be arcuately shaped as shown in Fig. 7, to accommodate this movement.

By arranging the coils longitudinally of the handle l am enabled to produce these coils in a size and arrangement which will permit 'of their'being mounted in a handle suiciently small to be comfortable in the hand out the user and at the same time impart to the coils qualities which will permit of their continuous operation through comparative long periods of time without objectionable increase in temperature.

' lBy mounting the armature so that its vmovement is toward and away from the axis of each coil,lllA eliminate the necessity for a bell crank or similar motion translating mechanism.

By mounting the armature as shown in all the figures except Fig. 5, the travel of the armature from and toward the pole pieces is uniform with relation to each pole piece so that the magnetic pull of each le piece is effective to move the movable clipper blade, Where as if a bell crank were employedto move the clipper blade transversely of the' handle while the armature moves longitudinally thereof a portion or the magneticpull wouldfbe lost by reason of the nearness of one end of the amature to the pivotal center.

and its equivalent in Figs. 3 and 4l maybe mounted so that its tension may be Varied as by a screw similar to the-screw 19 of Fig. 5. Again the movable member 10 may be depended upon to hold the movable clipper blade into proper operating contact with the stationary blade, or the springs 25 of Figs. 6 and 7 may be mounted on the construction of the other igures to hold the clipper blades in proper operatingcontact, and it 1s obvious that these springs may be adjustable or may be replaced by adjustable members' which are not the nature of springs, these modifications being so obvious that it has not been deemed necessary to illustrate them.
